ASR 26 returns a Compatibility Feature Register (CFR) when the
crypto feature is on. Without the crypto feature, a read keeps
strand status as before.
Reports AES, SHA1, SHA256, SHA512, CRC32C.
IIUC to keep the series bisectable, this patch should be

Guests can read the CFR before using each crypto instruction.
Based on OSA (Oracle SPARC Architecture) 2011:
- 5.5 (Ancillary State Registers), table 5-8
- 5.5.11 Compatibility Feature Register (CFR), table 5-15
